Min­er­alien­por­trait Stib­nitDas Mineral Antimonit, ein Synonym für Stibnit, bzw. das daraus gewonnene Antimon, wurde bereits in der Bronzezeit, seit etwa 3000 v.Chr. als Zuschlag zu Kupfer verwendet, um Bronze herzustellen. Die Babylonier verwendeten es zum Dekorieren von Lehmziegeln. In China vor über 3000 Jahren v.Chr., in Babylon und Ägypten vor über 2000 Jahren v.Chr. und im alten Rom wurde pulverisierter Antimonit entweder als Puder oder, mit Ölen bzw. Fett gemischt, als Haar- und Augenbrauenfarbe sowie als Schminke (Eyeliner) benutzt, um die Augen größer erscheinen zu lassen. Diese Verwendung hielt bis gegen Ende des 19. Jh. in China und Japan an. In anderen Ländern, in welchen kein Antimonit vorkam, benutzte man Galenit als Schminke. Wann Antimon erstmalig zur Beschichtung von Kupfer sowie zum Scheiden von Gold und Silber angewendet wurde, ist nicht datierbar. - Ein Beitarg von Peter Seroka

Der Koch­er­s­tollen im Wölsen­dor­fer Re­vi­erBei dem Kocherstollen handelte es sich um einen 150 m langen, fast waagerecht in den Berg getriebenen Stollen; daran schloß sich ein sogenannter Bremsberg von vielleicht 50 m Länge an, der in eine Tiefe von circa 30 m führte. Vom Ende dieses Bremsberges aus wurden 2 Strecken aufgefahren, die eine in nordwestlicher und die andere in südöstlicher Richtung. Die NWstrecke erreichte eine Länge von etwa 60 m, die SEstrecke eine solche von etwa 250 m. Von der NWstrecke war ein sogenannter Überhau (Luftloch) bis über Tage herausgearbeitet worden. Die Gänge wurden in den oberen Partien abgebaut, waren zum Schluß aber nur noch 25 - 30 cm mächtig und damit nicht mehr ... Ein Beitrag von Michael Kommer

"Ober­fränkisch­es Re­vi­er" a min­ing por­traitThe mining in the Franconian Forest has produced a lot of pits in the area and counts to the oldest mining areas in Germany. Indeed, one searches in the World Wide web in vain according to the information of which are documented by photos or maps.

Min­er­al Por­trait CalciteCalcite is one of the most abundant natural minerals. It is found in very different shapes, both compact as limestone as well as sinter in caves and in the crystalline state. But even in our daily life calcite is always present: in some regions it blockes water pipes as "chalk", we build our houses with it, it is in our food chain and without it we could not stand upright.

Calcite is not rare, but the varied mineral on Earth. The variety of forms and variations of the forms of calcite are unmatched in the world of mineralogy. By 2009, more than 800 Calcit forms have been described.

Min­er­al Por­trait PyriteThe term used in the plural "pyrites" has often been misused in the past or in common for marcasite, chalcopyrite, pyrrhotite and other yellow to brass-colored minerals. The word pyrite is derived from the Greek "pyrites lithos" (derived pyr = fire and lithos = stone) and describes a characteristic of the mineral, when rubbing against steel or flint (flint) to generate sparks. In prehistoric tombs pyrite concretions and unrolled pyrite where found, which supposed to be used for lighting a fire. (Article in German)

The Franken­holz Mine – A Hid­den Chapter of In­dus­trial His­to­ryFrom early tunnel construction in the 18th century to its final closure in the 1950s, the Frankenholz Mine in Germany’s Saar region was a key site of coal mining history. With ambitious shaft projects, its own cableway connection to Bexbach, and remarkable geological features – including fossil discoveries and natural oil seepages – the mine reflects both the rise of industrial progress and the dangers of underground work. Gas explosions, water ingress, and tragic accidents shaped the lives of thousands of miners. Frankenholz remains a compelling reminder of a bygone mining era.

Al­ten­berg Tin MineThe Altenberg tin mine is well known for its huge surface break left by the mining activities. Among mineral collectors the mine is famous as well for its unique Pycnite deposit, a variety of topaz occurring in massive columnar aggregates up to a length of 30 cm.

The mining started in 1440 and continued, with several ups and downs and some total shut-down periods, until 1991. The mining activities aimed for a plutonic granite body (350 to 400 metre in diameter and hydrothermally mineralized mainly with cassiterite and smaller amounts of wolframite, molybdenite, arsenopyrite, bismuth and others) and managed to extract a total sum of 37 million tons of ore. The huge surface break, called "The Altenberger Pinge", is the result of several roof collapses caused by excessive ore excavation and later on the continued drawing of caved material from the bottom of the fracture zone.

Collectible minerals were rare and small, so the Altenberg tin mine became never as famous as the Freiberg or Ehrenfriedersdorf districts, but its unique geology and mining technology made it quite interesting and worth a closer look.
